Don't expect to see Mulan in a pretty getup when we first meet Disney's warrior princess in Once Upon a Time's September 30 premiere. She'll be armored up and battle-ready. "I go on a journey with Prince Phillip to find his princess, Aurora," teases Mulan's portrayer, Jamie Chung (Sucker Punch). "There's this evil spirit that's moving and my character ends up bonding with Sleeping Beauty. And as you've heard, Captain Hook is joining us."
